This study examines the relationship between education outcomes, health outcomes and economic growth in Nigeria covering the period of 1980–2014 by employing secondary enrolment rate and under-five mortality rate in the analysis. Error correction mechanism was employed, and results show that secondary enrolment and under-five mortality rate have long-run relationship with economic growth. The interaction variables are statistically significant though exacted negative impact on economic growth, implying that interaction variables may not impact directly on economic growth but could have indirect positive impact on the economy through other variables such as employment. If enough funds are allocated to education and health and judiciously maximised, Nigerian economy will experience more growth. The conclusion that emerges from this paper is that Nigerian government needs to stimulate more investment in education and health for more growth considering the complementary relationship between them.
